RAIL CHAIR.

Patented Apr. 4, 1922.

Application led February 2, 1922. Serial No. 533,512..

To all ywhom 'it may concern.' y

Be it known that I, CHAnLns MAL-iron, a citizen of the United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Rail Chairs, of which the following is a specification.

My present invention, which relates generally to that type of rail joints of boltless construction, more especially has reference to improvements on the form of rail chair disclosed in my Patent #1,390,919, dated September 13, 1921, and primarily my said present invention has for its purpose to render the construction of the stated patented rail chair more economical, in which the parts are especially designed for facilitatinfr the practical application of the chair, anl for holding the said parts in condition to more effectively' serve their intended purposes.

In my patented rail chair stated, three spikes are used for holding the chair down onto the wooden tie, and these are usually so applied, that when fitting the cha-ir or shoe under a rail base it is necessary to draw the several spikes, and by reason there of it has required some time and much inconvenience, when assembling the parts that constitute the chair, to their operative condition.

One of the objects of my present invention is to produce an improved arrangement of chair or shoe section, that provides tor conveniently, quickly and effectively plac ing the chair or shoe in the desired operative position without the need of drawing all of the spikes, as before mentioned, and in which means is provided for interlockably holding the parts, that constitute the chair, vin operative engagement with each other, and with the base of the rail sections that rest thereon. n

Again, my present invention, in its more complete make-up, embodies an improved cooperative combination of opposing shoe or chair members and steel wedgeslfor interlocking with the web of the abutting rail sections, combined with an improved arrangement of wooden wedges, and means for holding all of the parts against undue vibration and in a dposition from which they are not readily isplaced under the usual strainl transmitted to the chair connection, from passing trains.

.Among other minor objects in view, that will hereinafter appear, as the detailed description of the parts is considered, my present invention consists in the improved arrangement and peculiar features of construction hereinafter explained, specifically stated in the appended claims, 'and illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of a preferred form of my improved rail chair.

Figure 2 is a horizontal section thereof taken substantially on the line 2 2 of Fig ure 3.

Figure 3 is a cross section of the same on the line 3 3 of Figure 2.

Figure 4L is a fragmentary horizontal section showing a modified form of the invention.

Figure 5 is a cross section of the modiied form of chair or shoe kshown in Figure 4.

In my present rail chair construction, the chair or shoe, in practice, is preferably ten inches long and when operatively applied it is adapted to sit down into a recess or seat 7, in the top of the wooden cross tie 7, and the said chair or shoe, as in my patented construction referred to, is secured upon the tie b y a pair of spikes 5 5k at one side and a midway positioned single spike 5.a' at the opposite side of the chair, as shown.

1n the preferred construction, shown in Figures 1 to 3, the chair is formed of two half sections 2 2, each of which includes an upwardly extending web 2b, and the said webs 2b of the opposing chair sections 2, are parallelly disposed, with their inner faces in parallel planes with'respect to eachother, as is best shown in Figure 2.

In my present and preferred construction of rail chair a combination of wooden and steel wedge members is employed, and these are arranged as best shown in Figures2 and 3, by reference to which it will be observed the steel wedges 3 3 'are disposed in reversed directions andweach has one face formed with upper and lower flanges 30 that provide longitudinal grooves or seats 31 for receiving spacers or bearing blocks 32 which are of wood kof uniform thickness throughout and that provide for effecting a gripping of the parts when the steel wedges 3 3 are driven home, as will hereinafter be further explained.

',Ihe inner face of each Ychair web 2b is formed with a longitudinal seat or recess 21 for the reception of supplemental Wooden wedges 4-4, the latter being oppositely positioned, relatively to each other, (see Figure 2) to provide for the desired wedging of the coacting members 3--32-4 with each other and with the chair webs 2" and the web 6 of the meeting ends of the rail sections '60.

In my present form of rail chair, means is provided to hold the steel Wedges 3 from slipping back or working loose after they have been .driven toeil'ect the clamping a'ction of the parts andthe said means comprises friction elements in the nature of strips of tar papery 8, one of said strips being interposed between the adjacent faces of the steel Wedges 3 and vtheir coactinlg Wooden Wedges 4, as is clearly shown in wigures 2 and 3. The steel Wedges 3, in my present construction of rail chair are' somewhat longer than the opposing chair sections, the lwooden fillers 32 and the wooden Wedges 4 t0 facilitate the driving or removal of the said Wedges 3, as conditions may make necessary and when the chair body is made of two sections, as shown in Figures l, 2 and 3, the Wooden Wedges 4 are held from slipping or Working endwise by the flanges 20 that constitute the ends of the recesses 2l in the chair Webs 2b. Y Y

VAs before stated, in the practical applica tion of my patented rail chair, before mentioned,l in case it is desired to disconnect the chair for slipping it under rail ends to be seated thereon, end to end, the three spikes must be drawn to `allow for the desired adjustment of the parts mentioned. 1n my present construction, by reason of the chair bein composed of tivo opposing half sections, W en it is desired to take out and replace a rail, .to provide for such result, it isonly necessary to draw the single spike at one side and then pull the chair section, atA that side, lateral-ly from the rail 4and `from `the opposing chair section.` t

The freeends of the base portion22 of the `chairsections have their cci-engaging edges formed with interlocking elementsen- '-ngeach other when they'are adjusted an position to'serve as a chair for receiving Itheadjacent rail ends thereof, and for such "purpose the `outer, base edge of one `sect-ion cnt down to form a somewhat resilient tongue lthatmay, and preferably does, cxtenti Athe Stull length ofthe said base edge and at intervals such tongue 23js` provided with ilrpwardly projected locking. lugs 124,

that haveouterbevelled faces 24a to facilitate slipping under "a like :resilient `portion `S36 onathebasevedge of thefopposing chair sec,u Y

itiomeft'heysaid'portion 26, ,at suitable inmais, having locking slots 27, intoVWhich the-lockin lugs 24 of the tongue 28 on the opposing c airseetion venteras the two' halt sections of the chair are closedv together, it being understood that in my present Vconstruction of rail chair, after the chair and rail ends are connected as described, the chair is held secured on the tie by driving the spikes 5 5 and 5, as in my patented construction before referred to.

In the present construction, to further secure the parts from rattling and against any tendency to pull apart or separate from the desired interlocked condition the Webs 2h, the steel land the wooden Wedges 3l and 4, the wooden spacers 32 and the intervening paper strips 8 Vare' each :formed with elongated horizontal apertures 28, 38, 40, 45 and 46,y adaptedfor being brought `intoregister with each other and with circular .apertures 6l in the websof the adjacent rail ends, into which apertures are swedged pins 62 whose opposite ends pass through the aforesaid :reg istering elongated slots in the Wedge mex-n bers, the paper strip and the webs 2b of the chair sections. as clearly shown i-n Figures 2 and-3 of the drawing, from which Iit `:also will be noticed that provision is made for the expansion Vand contraction of the rail ends, as the pins 62 tend at all times to hold the Vchair andthe rail ends in rigid relation relatively to the up andddwn sagging ofV the rail during the passage'of the `heavy trains thereover. j

Vhen the chair is assolid body, `as in my modified form, indicated inFigures `4 `,and 5 ofthe drawings, to disconnect the chair from the rails, it is necessary to drawthe three spikes. In the saidjmodiied form, the chair Webs 2b are constructed without the longitudinal sea-ts 21, that is, with fiat faces against which the wooden Wedges seat, and the latter are held in atighteng `ent with the said inner faces of the webs 2* when the-steel wedges 3 `are driven home. by

Vvertical ribs 25, -V shaped in cross section.

The relation ofthe steel Wedges 3, the wooden Wedges 4, `the; tarrcpaper 'strips8 and the wooden spacers32 are cooperatively -assembled the same as inthe preferred eon struction shown and described.

'-From the foregoing descript1on,taken in .connection with the drawings, the complete construction, the manner in which .the chair when necessary will be readily apparentto those familiar with the construction and Vuse of rail chairsof the `type to which `my present inventionfrelates anda further de-V tailed description thereof is therefore deemedV spiked onto tie, the saidbase having ai seat,
